So have you guys tried this? I'll admit that I am kind of a Long Tail Cast On weenie. I use it for everything, sometimes even if a pattern calls for something else. I did learn the Old Norwegian Cast on for Vaila, and I was feeling pretty good about myself.
So my new sweater, Lusekofte, asks for the provisional cast on for the sleeves so they can be hemmed and I JUST COULD NOT DO IT! It took me a few tries to figure out how to do it, and then when I finally got it, I just couldn't join in the round. I guess part of the problem is that I'm knitting these sleeves using Magic Loop, which I usually love, but getting that first stitch knit and holding onto the waste yarn and not twisting it was too much for me. I finally got everything fine and when I got to the second round I realized I had twisted it!
So I gave up and did the regular long tail cast on. I figure in the end, if sewing down the hem makes a large ridge, I can try to unpick the cast on and sew down the live stitches. But the hem is 3.5" so I don't think it will matter.
It is a little disconcerting to be unable to complete the FIRST LINE OF THE PATTERN!!!
